Bought the original helmet and RE jacket at their showroom in chennai. They have tons of accessories like t-shirts, pants, boots, goggles etc. Also test-rode the GT. It is a sweet ride.
The corbin seat is very nice. It is lower than the stock, and their memory foam conforms to your butt after 500 miles of riding. The passenger seat and backrest is especially plush and comforting. Since the height is at least 1.5 inches lower than stock and you sit a little further away from the tank, it needs some time to get used to it. Squeezing your thighs around the rubber pads is more difficult unless you sit close to the tank (at least for my height).
